The Sassenage Cisterns, or ‘les cuves’ is an underground river located outside of the city of Grenoble. The cisterns were formed and shaped over a million years ago by the water than runs through it. Tour guides take travelers down to the majestic underground world where they are quite literally in the center of the earth. The sounds of the flowing river can be heard while the natural wonders of the cave capture the eye. The Sassenage Cisterns opened to visitors in 1947, and over the years it became more accessible and now has over one kilometer of walking paths.
